predicate pushdown does not work correctly with outer joins
-----------------------------------------------------------
Key: HIVE-1534
URL: https://issues.apache.org/jira/browse/HIVE-1534
Project: Hadoop Hive
Issue Type: Bug
Components: Query Processor
Reporter: Amareshwari Sriramadasu
The hive documentation for predicate pushdown says:
Left outer join: predicates on the left side aliases are pushed
Right outer join: predicates on the right side aliases are pushed
But, this pushdown should not happen for AND predicates in join queries:
ex: SELECT * FROM T1 JOIN T2 ON (T1.c1=T2.c2 AND T1.c1 < 10)
